The overloaded bridge collapsed under the weight of the throng and an estimated 4 000 Portuguese civilians and French legionnaires drowned in the Douro River caused the 335 foot long
why bridges fall Fire Historically more bridges were made of wood and were much more susceptible to fire This was particularly true of old fashioned train bridges where the spark created by the steel wheels and steel tracks could sometimes cause a bridge to catch fire and burn to the ground
A trio of new investigations is underway Monday to see who might be responsible for the deadly Baltimore bridge collapse that killed six people destroyed a major thoroughfare and crippled the
The jaw dropping collapse of Baltimore s well trafficked Francis Scott Key Bridge resulted after a rare set of circumstances — but still highlights how shipping and structural changes could
The analysis indicated that the bridge collapse is mostly caused by natural disaster Especially the flood is a main cause besides earthquake Unreasonable construction scheme is the main causes in artificial factors and the collapses of overload and collision has a large proportion in total According to the bridge attribute information arch

The Quebec Bridge was the longest cantilever structure attempted until that time In its final design the clear span was m 1 800 ft long The bridge project was financially troubled from the beginning This caused many setbacks in the design and construction Construction finally began in October 1900
This paper is intended to review the main causes and mechanisms of bridge collapse The common factors resulting in bridge collapse are first reviewed
The most iconic example of such a failure is the collapse of the Tacoma Narrows Bridge in 1940 when the right wind condition drove the bridge to its resonance frequency [1] Since the structures
That s not a problem that s likely to cause collapse but the type that is likely to cause collapse is the rusting of the main members of the bridge the truss members that were supporting the

The pivotal event in the bridge s collapse said the Board was the change from vertical waves to the destructive twisting torsional motion This event was associated with the slippage of the cable band on the north cable at mid span The twisting bridge deck caused the wind flow separation to increase This formed a vortex or swirling
The bridge deck s twisting motion began to control the wind vortex so the two were synchronized The structure s twisting movements became self generating In other words the forces acting on the bridge were no longer caused by wind The bridge deck s own motion produced the forces Engineers call this "self excited" motion
